UNITED STATES PATENT OEEIcnA JOHN R. RENNOUS, OF BALTIMORE, MARYLAND.

BRUSH.

SPECIFICATION forming part of Letters Patent No. 250,577, dated December 6, 1881. 'Application med october 2a, 1881. (No model.)

To all whom it may concern Be it known that I, J oHN R. RENNoUs, of the city of Baltimore, and State of Maryland, have invented certain Improvements in Brushes, of which the following is a specification.

The object of this invention is to produce whatiskuown to thetradeasa solid or fullcenter77 paint-brush; and itconsists, primarily, in attaching to the handle, which is driven through the mass of bristles and the head-block surrounded by the ferrule, a supplemental brush which practically tlls the central space in the mass ot' bristles formed bythe said handle.

Itfurther consi.-ts in the manner of constructing the central hush, and in the means whereby it is fastened to the handle aforesaid.

In the further description of my said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in which- Figure I is a sectional view ot' the improved brush. Figs. II, III, IV, and V are details of the brush, hereinafter fully described.

Similar letters of reference indicate similar parts in all the views.

A is a ferrule, and B the head-block, with which the butts of the bristles come in contact.

O O are the exterior bristles, which, in connection with the ferrule and block before alluded to and the handle, form the brush proper. I) are the bristles of the central or supplemental brush secured to a holder, E, which, in turn, is attached to the handle F. The holder E consists of a flanged thimble, a, into which the bristles D are inserted, and it is fastened to the said bristles by means of a tapering plug, b, which is driven between and among them from their butt-ends and a plate, c, the edge of which is crimped over the flange of the thimble. Fig. I represents a completed brush. Fig. II shows the central bristles, D, inserted in the thimble, and secured therein by means of the tapering plug b. Fig. III shows the plate c fastened to the butt of the handle by means of a screw, d, and a small tack or nail to prevent its turning, and in a condition to receive the thimble and its contents. A tool, G, (shown in Fig. III,) is adapted to crimp the edge of the plate over the flan ge when struck with a hammer.

It will be understood that in order to admit of the ready application of the tool F to the bristles D the ends of the bristles are first Wrapped with twine, as shown in Figs. II, 1V, and V. Fg.V shows the brush in the last stage ot' manufacture-viz., that wherein the two completed parts ot' the brush are united. In this last operation a tool, H, corresponding with the one, Gr, except that it is devoid ofthe inclined edge, is used to force the brush-hanl dle, with its accompanyingsupplemental brush, toits proper position with reference to the brush proper, and at the same time complete the crimping of the edge ot' the plate c over the flange of the thimble. It desired, the crimp may be completed by means of the tool G before the handle is placed in position in the brush proper.

By making the thilnble a smaller than the butt-end of the handle. an annular space is formed in the bristles. This space, which can be omitted by increasing the size of the thimble, is considered by some a decided advantage tothe brush, but by others unnecessary. I do not therefore limit myself to either construction. v-

I claim as my inventionl. In combination with the handle ofa paintbrush made separate from the head-block and adapted to be driven through the bristles and the head-block to secure the. former within the ferrule, a supplemental brush which consists of a mass of bristles having a solid or full center, fastened within a ferrule by means of a plug driven into the said bristles from the buttend thereof, substantially as and for the purpose specitied.

2. As means for securing the bristles D of 9o the supplemental brush to the handle F, the flanged thimble c and plate c, the edge of the latter being crimped over the ange of the former, and the screwT or nail d, all arranged substantially as specified.

JOHN R. RENNOUS.
